COMBOSITION FOR REPAIRING LEAKS.

. {It is another object of this invention to provide a leak stoppingcomposition for hot Water circulating systems which Wlll not only repairall leaks which may be present 1n the s stem at the time thiscomposition 1s place therein, but which will prevent leaks from formingwhile this composition is in the system, and which will also keep the1nterior of the system cleansed and in goodcondition.

I attain the above stated objects by mixing a composition of aluminum,flax seed meal, trisodium phosphate, soda ash and soap and placing thesame in the hot water circulating system. The above ingredients Wlllproduct '30 the desired effects when the proportions are varied greatly,but I find that the most desirable proportionsare as follows:

Percent. Aluminum Flax seed meal 5O Tri-so dium phosphate 15 Soda ash Al2 Soap 11 40 When this composition is placed in a hot water circulatingsystem containing aquar tity of watenthe last three named ingredientsdissolve and form a colloidal solution. The soap, stimulated andstrengthened in its action by the tri-sodium phosphate and the soda ash,exerts a strong suspending and cleansing action. The suspending actionprevents the agglomeration of the insoluble materials in'the mixture,and therefore, prevents the stoppage of the circulatory system.

The insoluble materials are left as a somewhat fluffy mixture and arestirred up by the circulation of the system.- The suspended particleswork their way into the leaks in the Application filed April 12, 1927.Serial No. 183,243.

The moderately alkaline solution prevents any separation of the fattyacids of the soap and helps to prevent the formation of any oily orgreasy deposit on the inner walls of the hot water circulating system.The phosphate, the carbonate and the soap produce a very efficientsuspending agent for the insoluble matter, and also have a verysatisfactory cleansing action on the interior of the hot watercirculating system.-

If the soda ash were. omitted from the mixture the solution would not bequite as alkaline, and the action of the aluminum would be somewhatlessened, which would be quite desirable in aluminum head engines. Alsothe sealing of the leaks would be accomplished more by the aluminumphosphate and less by the other compounds if the soda ash were omitted.

In the specification I have set forth a preferred embodiment-of myinvention, and although specific terms are employed, they are used in ageneric and descriptive sense, and not for purposes of limitation, thescope of the invention being set forth in the appended claims.

I claim:

1. A composition for stopping leaks in hot water circulating systemscomprising a mixture of aluminum, flax seed meal, tri-sodium phosphate,soda ash and soap.

2. A composition for stopping leaksin hot water circulating systemscomprising a mixture of aluminum, flax seed meal, trisodium phosphateand soap.

3. A composition for stopping leaks in hot water circulating systemscomprising a mix-- ture of aluminum, flax seed, soda ash and trisodiumphosphate.

In testimony whereof I affix my signature.

GEORGE I. RAY.
